Some people have noticed that the internet offers plentiful opportunities to make money. Some methods will not make you much money - for example paid-to-click ads are a waste of time. Other methods require large investments or knowledge - for example if you want to invest in stocks you need thousands of dollars and you need to have some insider information.
Some methods should be avoided because they use a "pyramid" scheme. You are required to buy an expensive product (such as cosmetics, dietary supplements or even life insurance). This allows you to enter the system and your job is to offer the same product to other people. It is needless to say, that 95% of people won't sell anything and they will only lose money because they bought an expensive product they don't need.
There's not many methods that don't require any special skills but this method is one of them. This method is not known by many people and was secret until recently. However that doesn't mean it is something inaccessible. It can be used by anyone. Another advantage is that the method is available for free - there are no fees and all the information is absolutely free.
